- Stove Collar and Dampen.

N0. 89,179, Patented April 20, 1869 alum/r1 (D/5% 5mm Mam WW JAMESSPEAR, OF PHILADELPHIA, PENNSYLVANIA.

Letters Patent No. 89,179, dated April 20, 1869.

strove-COLLAR AND DAMPER.

' The Schedule referred to in these Letters Patent and making part ofthe same.

To all whom it may concern:

Be it known that I, JAMES SPEAK, of No. 1116 Market street,Philadelphia, Pennsylvania, have invented a certain new and usefulStove-Collar and Damper.

The nature of myinvention consists in making the damper, collar, andpipe, of oast-iron, and in three pieces, of such a form as to facilitatethe construction of the damper, and adapt it as a permanent attachmentto the stove. I

The stove-pipe damper, as commonly made, is a section "of sheet-ironpipe, with holes drilled through for the pivot of the damper. It isfitted with difiiculty, and is easily lost in taking down a stove forthe summer. Also, the bearing for the pivot of the damper, being only insheet-iron, is soon Worn so loose that the damper is frequently turnedby a puii' of wind.

By my invention, the damper becomes a permanent part of the stove,avoiding the use of a damper in a sectionof the stove-pipe.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation. I

Figure 1 shows the section to be attached to the stove.

Figure 2 is the section to be attached to the stoveplpe.

Figure 3 is the damper.

Figure 4 shows the collar and damper complete, as attached to thecylinder.

Figure 5 is another modification of theinvention.

The collar A, fig. 1, is cast with an indentation, a on each side, intowhich fits the pivot c of the damper.

The flange a is cast on one end of the collar, by which it is riveted tothe sheet-iron cylinder D.

A short section of cast-iron, B, fig. 2, is cast with a socket, b, onone end, having similar indentations, a corresponding with those incollar A.

The other end, I), is fitted to receive the stove-pipe.

The socket b is east tapering, so that the collar A slips into itwithout any fitting.

' The damper C is cast circular, having a pivot, c,

and tum-buckle 0*, all in one piece.

The pivot c is placed in the groove c of thecollar. The section B isthen riveted upon the collar A, securing the damper O in its place. Thearticle com- 1 plete, as shown in fig. 4, is then riveted to thesheetiron cylinder D.

What I claim as my invention, and desire to secure by Letters Patent,is- I The construction and combination of the three castiron pieces, A BC, so as to form a stove-pipe collar and damper, as herein described.
